Abstract Two new dammarane-type triterpenoids, notoginsenoside SY1 (1) and notoginsenoside SY2 (2), were isolated from the stems and leaves of Panax notoginseng. Their structures were elucidated to be 3β, 12β-dihydroxy-22, 23, 24, 25, 26, 27-hexanordammarane-20-one 3-O-β-D-xylopyranosyl-(1→2)-O-β-D-glucopyranosyl-(1→2)-O-β-D-glucopyranoside (1), 3β, 12β-dihydroxy-20S, 24 R-epoxydammar-25-ene 3-O-β
抽象的 从三七茎叶中分离得到两个新的达玛烷型三萜化合物,三七皂苷SY1( 1 )和三七皂苷SY2( 2 )。它们的结构被阐明为 3 β , 12 β -二羟基-22, 23, 24, 25, 26, 27-hexanordammarane-20-one 3- O - β -D-xylopyranosyl-(1→2)- O - β -D-吡喃葡萄糖基-(1→2)- O - β -D-吡喃葡萄糖苷 ( 1 ), 3 β , 12 β -二羟基-20 S , 24 R -环氧达玛-25-烯 3- O - β -D-吡喃木糖基-(1→2) -O - β -D-吡喃葡萄糖基-(1→2) -O - β -D-吡喃葡萄糖苷( 2 )通过IR、HRESIMS和NMR实验得到。
